I have a question. For HD streaming I have now set up my PS3 directly with an ethernet cable from my mac because the router is to far away from the mac and PS3. (so, wireless internet on mac, cable to PS3 for PMS)

But, now I want to install a NAS server. So my set up would be (if that's possible, that's the question):

Will this work? Since the wireless repeater is the "second" router in the system... Will this be able to give ip's and everything it needs and still be able stream HD video?(I thought a wireless repeater would be the best option to have 4 ethernet ports, otherwise, a normal switch needs an input (no?))
